Technical field

The present invention relates to the Security element for cheque paper, value document etc., relate to the value document with this Security element, and relate to the method for the manufacture of this Security element.

Background technology

Object to be protected is usually provided with Security element, and it allows the authenticity of inspection object, is used as the protection to unauthorized copying simultaneously.

Object to be protected is such as cheque paper, identity document and the Product Validation element such as value document (such as banknote, chip card, passport, identity card, ID card, stock, investment securities, contract, receipt, check, admission ticket, credit card, health card etc.) and such as label, strip of paper used for sealing, package.

General especially and technology that is that give three-dimensional appearance in fact smooth paillon foil relates to various forms of holography in the field of Security element.But this technology has some shortcomings for the use of anti-counterfeiting characteristic particularly on banknote.On the one hand, the illustrated quality of the three-dimensional of hologram depends on lighting condition to a great extent.The diagram of hologram is usually difficult to identify, particularly in diffuse illumination.In addition, hologram has such shortcoming, and namely they are present in the many places in daily life simultaneously, and therefore, they disappear as the special status of anti-counterfeiting characteristic.

Summary of the invention

On those bases, the present invention is based on the object of the shortcoming avoiding prior art, and provide a kind of Security element for cheque paper, value document etc. especially, it, while the extremely flat configuration as Security element, obtains good three-dimensional appearance.

According to the present invention, this object is achieved by a kind of Security element for cheque paper, value document etc., described Security element has: the carrier with the surf zone being divided into multiple pixel, described multiple pixel comprises little of at least one optical activity respectively, wherein most of pixel has respectively for little identical of several optical activities of each pixel orientation, and described little planar orientation becomes to make described surf zone observed person can be felt as the region of giving prominence to relative to its actual spatial form and/or retreating.

This makes it possible to provide extremely flat Security element, and wherein such as the maximum height of little is not more than 10 μm, but still generates extraordinary three dimensional impression when observing.Therefore, it is possible to be that Observer draws up the region with strong protrusion outward appearance by means of the surf zone that (on naked eyes) are smooth.Substantially the three-dimensional structure of any shaping can feeling region can be generated by this way.Therefore, it is possible to simulate personage, object, figure (motif) or there is other object of three-dimensional appearance.Three dimensional impression is here always relative to the real space shape of surf zone.Therefore, surf zone self can have flat configuration or have bending structure.But, always obtain three-dimensional appearance relative to this basal region shape, so that for observer, so surf zone does not present the same with surf zone self smooth or bending.

Surf zone that is outstanding and/or back off area can be perceived as here be interpreted as referring to that surf zone can be perceived as the region of protruding continuously especially.Therefore, described surf zone can be perceived as the region of the obvious projection of curved shape or the real space shape such as having and depart from this surf zone.By Security element of the present invention, therefore, it is possible to imitate out the surface of such as protruding by the corresponding reflex behavior of simulation.

Surf zone is continuous print surf zone particularly.But surf zone can also have gap or even comprise discontinuous part.Like this, surf zone can interweave with other anti-counterfeiting characteristic.Other anti-counterfeiting characteristic can relate to such as true colour hologram, so that observer can feel true colour hologram and the outstanding and/or back off area provided by surf zone of the present invention together.

Particularly, the orientation of described little is chosen to make described surf zone observed person can be felt as the region of non-flat forms.

The most of pixel had respectively for little identical of several optical activities of orientation each pixel can be 51% of pixel quantity.But described major part also can be greater than 60%, 70%, 80% of pixel quantity, or is greater than 90% especially.

In addition, also can be that whole pixels of surf zone have little of the identical several optical activities of orientation all respectively.

Little of optical activity can be configured to reflectivity and/or little of transmittance.

Described little can be formed in the surface of described carrier.In addition, little face also can be formed in upside and the downside of carrier, and toward each other.In this case, little face is preferably configured as little of the transmittance with refraction effect, and wherein carrier self is also transparent or at least translucent certainly.The size of little and be oriented in be chosen to make especially region can observed person be felt as relative to the upside of carrier and/or the real space shape of downside outstanding and/or retreat.

Carrier can be configured to stacked compound.In this case, little can be positioned on the interface of stacked compound.Therefore, little such as can be stamped into the impression paint be arranged on carrier foil, next be metallized, and embeds in another enamelled coating (such as protective paint or bonding paint).

Especially, in Security element of the present invention, little can be configured to embedded little.

Especially, described optical activity faceting formation becomes to make described pixel not have optical diffraction effect.

The size that optical activity is little can between 1 μm-300 μm, preferably between 3 μm-100 μm, between 5 μm-30 μm.Especially, preferably there is roughly ray optics reflex behavior or roughly ray optics refraction effect.

The size of pixel is so selected to make the area of the area ratio surf zone of pixel at least one order of magnitude little, preferably little at least two orders of magnitude.The area of surf zone and the area of the pixel direction being here interpreted as referring in particular to along the macro surface being orthogonal to surf zone projects a respective area during plane.

Especially, the size of pixel can be chosen to make size at least one order of magnitude little of the size of the pixel area in specific surface region at least in one direction, preferably little at least two orders of magnitude.

The maximum ductility of pixel is preferably between 5 μm of-5mm, is preferably between 10 μm-300 μm, is particularly preferably between 20 μm-100 μm.Primitive shape and/or Pixel Dimensions can change in Security element, but are not necessary.

(little can form periodic or acyclic grating to the screen periods of little of each pixel, such as sawtooth grating) preferably between 1 μm-300 μm or between 3 μm-300 μm, preferably between 3 μm-100 μm or between 5 μm-100 μm, particularly preferably between 5 μm-30 μm or between 10 μm-30 μm.Screen periods is chosen to make especially each pixel to comprise little of at least two same orientation, and diffracting effect in fact no longer works (such as from the wave-length coverage of 380nm-750nm) to incident light.Because the diffracting effect of or not in fact being correlated with occurs, little can be called little of no color differnece, or pixel is called no color differnece pixel, and this causes the reflection of directionality ground no color differnece.Therefore Security element has no color differnece reflectivity for little the optical grating construction existed by pixel.

Little face is preferably configured as the area constituent element (area element) of general planar.Faceting formation becomes the selected statement of the area constituent element of general planar, considers and usually always can not manufacture this fact of completely smooth area constituent element in practice owing to manufacturing reason.

The orientation of little is determined by their inclination angle and/or their azimuth especially.The orientation of little can certainly be determined by other parameter.Especially, involved parameter is two orthogonal parameters, two components of the normal vector of such as corresponding little.

On little, at least can form reflectivity or reflection enhancement coating (particularly metal or high refractiveness coating) in some region.Reflectivity or reflection enhancement coating can be the metal coatings of such as vapour deposition.As coating material, aluminium, gold, silver, copper, palladium, chromium, nickel and/or tungsten and their alloy can be adopted especially.Alternatively, reflectivity or reflection enhancement coating can by the coating formations of material with high index of refraction.

Reflectivity or reflection enhancement coating can be configured to partial transmission coating especially.

Again in an embodiment, on little, at least can form color displacement coating in some region.Color displacement coating can be configured to membrane system or thin film interference coatings especially.Here can realize the such as sequence of Jin Shu Ceng – Jie electricity Ceng – metal level or the sequence of three dielectric layers, wherein the refractive index in intermediate layer is lower than the refractive index of other two layers.As dielectric material, such as ZnS, SiO can be adopted 2, TiO 2/ MgF 2.

Color displacement coating also can be configured to interference light filter, be had the thin semi-transparent metal layer, nano particle etc. of selective transmission by plasma resonance effect.Color displacement layer also can be embodied as liquid crystal layer, diffractive embossment structure or sub-wave length grating especially.The membrane system be made up of reflecting layer, dielectric layer, absorbed layer (being formed on little with this order) is also possible.

Membrane system adds little not only can be configured to little/reflecting layer/dielectric layer/absorbed layer as mentioned above, but also is configured to little/absorbed layer/dielectric layer/reflecting layer.Its order depends on especially observes Security element by from which side.In addition, when membrane system adds faceting formation precedent as absorbed layer/dielectric layer/absorbed layer/little or absorbed layer/dielectric layer/reflecting layer/dielectric layer/absorbed layer/little, the color displacement effect being found in both sides is also possible.

Color displacement coating not only can be configured to membrane system, but also is configured to liquid crystal layer (particularly cholesterol crystalline state liquid crystal material is formed).

If simulate the object of diffuse scattering, then can carry out scattering coating or surface treatment to little face.According to the scattering of Lang Baite (Lambert) cosine law, or can there is the diffuse reflection with the angular distribution departing from cosine law in this coating or process.Especially, interested is here the scattering with remarkable preferential direction.

When being manufactured little by imprint process, the imprinting area of coining tool additionally can be provided with micro-structural to generate some effect, by described imprinting area, can the shape of little be impressed in carrier or carrier layer in.Such as, the imprinting area of coining tool can be provided with rough surface, occurs in the final product to have irreflexive little.

In addition, in Security element of the present invention, the screen periods of little can be chosen to for whole pixel be all identical.But, also can be that each or several in pixel has different screen periods.In addition, also can be that screen periods changes in pixel, from instead of constant.In addition, the phase information project for out of Memory project of encoding also can be impressed in screen periods.Especially, can arrange the inspection mask with optical grating construction, described optical grating construction has the cycle identical with little in Security element of the present invention and azimuth.In the part of inspection mask, grating can have the phase parameter identical with Security element to be tested, and has certain phase difference at other position.When checking mask to be placed on Security element, due to Moire effect, so zones of different will present different lightness or darkness.Especially, mask is checked can be arranged on the object to be protected identical with Security element of the present invention.

In Security element of the present invention, surf zone can be configured so that it observed person can be felt as virtual region.This is interpreted as referring to that Security element of the present invention demonstrates the reflex behavior that can not be seemed the Surface Creation protruded by real naked eyes especially.Especially, virtual region can be perceived as the rotating mirror making visible mirror image rotate such as 90 °.

This virtual region, particularly this rotating mirror, be highly susceptible to observer and detect and inspection.

In principle, the reflectivity of any real protrusion or transmissive surface can both transform virtual region as by means of the surf zone of Security element of the present invention.This can such as by changing, faceted azimuth (such as rotating to an angle) realizes.This makes it possible to obtain interesting effect.Such as, if all azimuth is all to right rotation 45 °, then, when directly throwing light on from top, surf zone is from upper right quarter raised zones shinny significantly for observer.If all azimuth all half-twists, then move along the direction vertical with the direction that observer expects when light is reflected in inclination.So the region (relative to surf zone) making observer no longer can determine to be perceived as protrusion is also such as exist towards front side or towards rear side by this factitious reflex behavior.

In addition, diffracting effect can be suppressed by acyclic grating or introducing random phase parameter by the mode of expection.

In addition, for the orientation of little, can be set, to simulate the surface such as with sub-light outward appearance " noise " (namely relative to treating that the optimum shape of simulated domain changes them slightly).Therefore, surf zone not only seems outstanding relative to its actual spatial form and/or retreats, and can also be given the quality of complete matching location.

In addition, except described surf zone, carrier can also have other surf zone preferably interweaved with a described surf zone, and is configured to other anti-counterfeiting characteristic especially.This structure can be called such as intertexture formula or multi-channel type image.Other surf zone is the same with a described surf zone also can be divided into the multiple pixels comprising little of at least one optical activity respectively, wherein most of pixel preferably has respectively for little identical of several optical activities of orientation each pixel, and little planar orientation becomes to make other surf zone observed person can be felt as and protrude or region that is outstanding and/or that retreat relative to its actual spatial form.This makes it possible to realize such as two different three-dimensional diagrams.

By means of intertexture, a described surf zone can be applied colouring information or the gray level information (such as based on sub-wave length grating, with the combination of such as true colour hologram or half tone image) of such as additional complete matching.

In addition, in the configuration of little, can hide or be stored as the phase information project of another Security element.

In Security element of the present invention, at least one little can have light scattering micro-structural in its surface.Several or whole little face can certainly have this light scattering micro-structural in faceted surface.

Such as, light scattering micro-structural can be configured to coating.Especially, little can be embedded, and be used as insert material, the light scattering micro-structural of expectation can be realized by it.

In the embodiment shown in fig. 1, Security element 1 of the present invention is integrated in banknote 2, makes Security element 1 from the front side of banknote 2 shown in Fig. 1.

Security element 1 is configured with the reflective security element 1 of rectangle gabarit, and the region 3 wherein limited by rectangle gabarit is divided into multiple reflective pixel 4, and the sub-fraction of described reflective pixel 4 illustrates enlargedly in as Fig. 2 of top view.

Pixel 4 is here square, and has the length of side be in 10 to hundreds of micrometer range.Preferably, the length of side is not more than 300 μm.Especially, it can be in the scope of 20-100 μm.

The length of side of pixel 4 is chosen to make the area ratio region 3 of each pixel 4 at least one order of magnitude little especially, preferably little two orders of magnitude.

Major part pixel 4 has the little face 5 of the identical several reflectivity of orientation respectively, and its medium and small face 5 is optical active areas of reflectivity sawtooth grating.

Figure 3 illustrates six neighbors 4 1, 4 2, 4 3, 4 4, 4 5with 4 6the sectional view of along the line 6, the diagram wherein in Fig. 3, as in other figure, for obtaining better representability, local is not actual proportions yet.In addition, the reflective coating on little face 5 is not shown in fig. 1-3, also not shown in the diagram, with simplicity of illustration.

The sawtooth grating of pixel 4 is formed in the surface 7 of carrier 8 here, wherein like this structurized surperficial 7 is preferably coated with reflective coating (not shown in Fig. 3).Carrier 8 can be the radiation curing plastics (UV resin) being such as applied to unshowned carrier foil (such as PET paillon foil).

As found out in figure 3, pixel 4 1, 4 2, 4 4, 4 5with 4 6have three little faces 5 respectively, the orientation of little is for each pixel 4 1, 4 2, 4 4, 4 5with 4 6identical respectively.The sawtooth grating of these pixels thus little face 5 is here identical, but their different inclination angle σ 1, σ 4except (in order to simplicity of illustration, only depict pixel 4 1, 4 4the inclination angle σ in a corresponding little face 5 1and σ 4).Pixel 4 3here only there is single little face 5.

When observing in top view (Fig. 2), pixel 4 1-4 6little face 5 be arranged in banded minute surface parallel to each other.Little being oriented in of face 5 is chosen to here: make 3 pairs, region observer can be felt as region that is outstanding relative to its reality (macroscopic view) spatial form (it is the form of flat site) and/or that retreat here.Here, what observer felt when watching little face 5 is the surface 9 shown in cross section in Fig. 3.This is that described little face 5 reflects the incident light L1 by selecting the orientation in little face 5 to realize, like the spatial form that to just look like it be according to the line 9 in Fig. 3 drops on region, as incident light L2 schematically shows.The reflection generated by the little face 5 of pixel 4 corresponds to the average reflection in the region on surface 9, and it is changed by respective pixel 4 or simulated.

In Security element 1 of the present invention, therefore the height profile of three-dimensional appearance is simulated by the configuration (being latticed here) of the reflectivity broached-tooth design (the little face 5 of each pixel 4) of the reflex behavior of imitation height profile.By region 3, therefore, it is possible to generate the figure that can dimensionally feel arbitrarily, the some parts of such as people, people, numeral or other object.

Except the gradient σ in individual little face 5, the azimuth angle alpha on simulation surface also will be conditioned.For pixel 4 1-4 6, be 0 ° relative to the azimuth angle alpha in direction arrow P 1 (Fig. 2) Suo Shi.For pixel 47, azimuth angle alpha is such as about 170 °.Pixel 4 7sawtooth grating schematically show with three-dimensional in the diagram.

In order to manufacture Security element 1, reflectivity broached-tooth design can such as by means of in GTG photoetching write photoresist, next development, electroforming, is impressed into UV and paints in (carrier) and to carry out the coating of mirror film.The coating of mirror film can such as realize by means of the metal level (such as vapour deposition) applied.Usually, the aluminium lamination of to be thickness be the such as 50nm of applying.Other metal can certainly be adopted, such as silver, copper, chromium, iron etc., or their alloy.Substituting as metal, also can apply high refractiveness coating, such as ZnS or TiO 2.Vapour deposition can on whole region.But, also can implement only to be arranged in some position or in latticed coating, so that Security element 1 is partly transparent or translucent.

In the simplest situation, the periods lambda in little face 5 is identical for all pixels 4.But, also can change the periods lambda in the little face 5 of each pixel 4.Therefore, such as pixel 4 7have than pixel 4 1-4 6little periods lambda (Fig. 2).Especially, the periods lambda in little face 5 can be selected randomly for each pixel.By changing the selection for the periods lambda of the sawtooth grating in little face 5, the observability that may exist coming across sawtooth grating diffration image can be made to minimize.

In a pixel 4, fixing periods lambda is set.But, substantially also can change periods lambda in pixel 4, make each pixel 4 there is acyclic sawtooth grating.

On the one hand, in order to avoid undesired diffracting effect, on the other hand, in order to make necessary foil thickness (thickness of carrier 8) minimize, the periods lambda in little face 5 is preferably between 3 μm-300 μm.Especially, be interposed between 5 μm-100 μm, the interval between wherein particularly preferably selecting 10 μm-30 μm.

In embodiment described here, pixel 4 is foursquare.But, also pixel 4 can be configured to rectangle.Also other primitive shape can be used, such as parallelogram or hexagonal pixels shape.Pixel 4 on the one hand preferably has the size larger than the interval in little face 5 here, on the other hand, little of making single pixel 4 can not uneasy Ground shock waves bore hole.The size range obtained from these demands is about ten to hundreds of micron.

So the gradient σ in the little face 5 in pixel 4 and azimuth angle alpha are produced by the gradient of simulated altitude profile 9.

Except gradient σ and azimuth angle alpha, phase parameter p can be introduced further for each pixel 4 alternatively i.So the surface relief of Security element 1 can with i-th pixel 4 iby following height function h i(x, y) describes:

h i(x,y)=A i[(-x·sinα i+y·cosα i+p i)modΛ i]

Here, A ithe amplitude of sawtooth grating, α iazimuth, and Λ iit is screen periods." mod " represents modular arithmetic, and obtains positive remainder when doing division.Amplitude factor A iproduced by the gradient of simulation surface profile 9.

By changing phase parameter p i, the sawtooth grating of different pixels 4 or little face 5 can be made relative to each other to offset.For parameter p i, can use for the different random value of each pixel 4 or other value.Therefore, it is possible to eliminate the potential visible diffraction pattern of (the little face 5 of each pixel 4) of sawtooth grating or the raster grating of pixel 4, itself otherwise undesired color effects can be caused.In addition, due to the phase parameter p of change i, the particular orientation that the sawtooth grating that also there is not neighbor 4 matches each other good or poor especially especially, this prevent visible anisotropy.

In Security element 1 of the present invention, the azimuth angle alpha in the little face 5 of each pixel 4 and gradient σ can be chosen to make them not correspond to simulation surface 9 as well as possible, but slightly depart from from it.For this reason, one-component (being preferably random) can be increased for each pixel 4 to according to the optimum value on suitable distribution simulation surface 9.Depend on the size of pixel 4 and the intensity (standard deviation of distribution) of noise, so different interesting effects can be obtained.When very tiny pixel 4 (about 20 μm), the surface of light presents sub-light gradually along with the increase of noise originally.When larger pixel (about 50 μm), obtain the outward appearance suitable with metallic paint.When very large pixel (hundreds of micron), each individual pixel 4 is told by bore hole.But so they look like as coarse level and smooth part, it lights brightly at different visual angles place.

Differently can select the intensity of noise for different pixels 4, enable the surface of protrusion outward appearance seem to have different smoothnesses or sub-luminosity at diverse location thus.Therefore, it is possible to generate such as observer to feel that region 3 seems the effect in the region of the level and smooth outstanding and/or retrogressing with sub-light inscription or quality.

In addition, color displacement coating, particularly membrane system can be applied to little face 5.Membrane system can have first, second, and third dielectric layer be such as laminated to each other, wherein first and third layer there is refractive index than the second floor height.Due to the different inclination angle in little face 5, when rotating Security element 1, observer can feel different colours.Therefore can feel that region has certain color spectrum.

Security element 1 can be configured to multichannel image especially, and it has the different regional areas be interlaced with one another, and at least one in wherein said regional area is formed in the manner of the present invention, observed person can be felt as three-dimensional regional area to make this regional area.Certainly other regional area also can be formed with described method by means of the pixel 4 with at least one little face 5.Other regional area is also passable, but non-essential, can be felt as the region of giving prominence to relative to real space shape and/or retreating.Intertexture can be such as checkerboard, or banded structure.Interesting effect can be obtained by the intertexture of several regional area.When the simulation of such as sphere interweaves with the diagram of numeral, this can carry out into the impression making number word observer to be arranged in the inside of the glass marble with half mirror surface.

Except above-mentioned employing color displacement coating, for Security element 1 of the present invention, additionally colouring information can also be set.Therefore, ink can such as be printed on little face 5 (transparent or thin), or is arranged at least in part below transparent or translucent broached-tooth design.Such as, the discoloring of figure represented by means of pixel 4 can be carried out thus.When such as simulating personage, ink layer can provide the color of face.

With the combination of true colour hologram or Kinegram, the intertexture of the true colour hologram of the color graphic on the surface 9 particularly simulated with pixel 4 with display is also possible.Therefore, the 3-D view of the essentially no aberration of object will present colour in some angle.

In addition, be also possible with the combination of sub-wave length grating.Especially, be favourable by the intertexture diagram of the identical figure of two kinds of technology, wherein the 3-D effect of broached-tooth design and the colouring information of sub-wave length grating combine.

The surface 9 simulated with pixel 4 can particularly so-called virtual region.This is interpreted as the formation of reflex behavior or the transmission behavior that can not generate with the reflectivity protruded really or transmissive surface here.

In order to further illustrate the concept of virtual region, in following introducing, and will be illustrated by the example of rotating mirror for the mathematical standard of demarcating with real estate.

When protrusion surface that is virtually reality like reality, the latter is describable by height function h (x, y).Here can suppose that function h (x, y) is differentiable (differentiable) (non-differentiable function can be gone out by differentiable function budgetary estimate, and it generates identical effect to observer the most at last).If ask now the integration of the gradient of h (x, y) along curve C closed arbitrarily, then integration will disappear:

In the mode of metaphor, this means that the difference in height that someone walks up and down along a closed path is identical, and finally land at identical At The Height.Therefore the difference in height sum overcome on the path is necessary for zero.

In Security element 1 of the present invention, the gradient in little face 5 and azimuth correspond to the gradient of height function.Can form such situation now, in fact gradient and the azimuth in its medium and small face 5 collide continuously each other, but can not find the height function making to disappear with upper integral.In this case, what speak of will be the simulation of virtual region.

A special embodiment is such as rotating mirror.About this point, first we will consider the simulation of true convex speculum with parabolic outlines.Height function is provided by following formula:

h(x,y)=-c(x 2+y 2)

Wherein c>0 is constant and determines the curvature of speculum.In this speculum, observer can see oneself the mirror image uprightly reduced.So the parameter of broached-tooth design is provided by following formula

α(x,y)=arctan(x,y)

With

A ( x , y ) = 2 c ( x 2 + y 2 )

If someone increases a constant angle δ to azimuth angle alpha now, then mirror image will just in time rotate this angle.Assuming that δ does not comprise the integral multiple of 180 °, thus virtual surface will be there is.If select such as δ=90 °, then mirror image is by half-twist, and acquisition can not smoothly to protrude the mirror image that real surface realizes.If make the gradient of h equal the gradient of broached-tooth design, then can find closed curve now, wherein not disappear with upper integral.Such as, edge is obtained with the curve K of radius R >0 around the circle at center

In the mode of metaphor, therefore this rotating mirror simulates such surface, and wherein someone upwards walks continuously along a circle, but finally lands at the At The Height identical with starting point.This real surface obviously can not exist.

For up to the present described Security element 1, it is assumed that regional structure becomes reflective area.But, when broached-tooth design or the pixel 4 (comprising carrier 8) with little face 5 transparent at least partially time, also roughly can obtain the same effect of three dimensional impression in transmission.Preferably, broached-tooth design is between two layers with different refractivity.In this case, so Security element 1 presents seem have the vitreum protruding surface to observer.

Described advantageous embodiment also goes for the transmittance structure of Security element 1.Therefore, such as, the rotating mirror of virtual region can image rotating in transmission.

The transmittance structure of Security element is described in detail below with reference to Figure 19-29.

The false proof resistance of Security element 1 of the present invention can by only under instrument visible further feature (it also can be called hiding feature) increased.

Therefore, additional information can such as be coded in the phase parameter of single pixel 4.Especially, can generate the inspection mask with optical grating construction, described optical grating construction has the cycle identical with Security element 1 of the present invention and azimuth.At the part in region, the grating of inspection mask can have the phase parameter identical with Security element to be tested, and has certain phase difference at other position.So these different parts present different lightness or darkness by Security element 1 with when checking mask stacked on top of each other by Moire effect.

Especially, mask is checked also can be arranged on banknote 2 or to be provided with in other element of Security element 1.

Except described contour shape, pixel 4 can also have other profile.So these profiles can to amplify glass or microscope is recognized.

In addition, other structure also can be embossed into or write in sub-fraction pixel 4 arbitrarily, replaces corresponding sawtooth or little face 5, and can not make it to impact bore hole.In this case, these pixels are not the parts in region 3, so the intertexture of domain of the existence 3 and differently composed pixel.Compared with the pixel 4 in region 3, these differently composed pixels can be such as every 100th pixels.Can in these pixels and in a subtle way printed patterns or icon, in 40 μm of large pixels, be such as incorporated to 10 μm of large letters.

In up to the present described embodiment, little is formed as making the minimum height values in all little faces 5 or minimum point (Fig. 3) be arranged in a plane in the surface 7 of carrier 8.But, also little face 5 can be formed as make the mean value of the height in all little faces 5 be in phase co-altitude, as schematically shown in Fig. 5.In addition, little face 5 can also be configured so that the maximum height value in all little face 5 of pixel 4 or peak value are in phase co-altitude, as schematically shown in Fig. 6.

Show cross section in the mode identical with Fig. 3 in the figure 7 to illustrate, but for pixel 4 4depict minute surface 10, it is in pixel 4 4region in simulation surface 9.When the Pixel Dimensions of such as 20 μm-100 μm, this minute surface 10 will undesirably cause the existence of large height d.When the mirror tilt angle of 45 °, corresponding minute surface 10 will be projected into outside x-y plane and reach 20 μm-100 μm.But the maximum height d of 10 μm preferably expects.Therefore, minute surface 10 is subject to mould d computing, to form the little face 5 drawn in the figure 7, the normal vector n in its medium and small face 5 corresponds to the normal vector n of minute surface 10.

Surface 9 to be simulated can be provided as such as one group of x, y value, and has the height h (3D bitmap) be associated respectively in the z-direction.Use this 3D bitmap, the square net or 60 ° of grids (Fig. 8,9) determined can be formed in an x-y plane.Each mesh point is connected, to use triangle tile (tile) to form area coverage in an x-y plane, as schematically shown in Fig. 8 and 9.At three corner points of each tile, take out h value from 3D bitmap.The minimum of a value in these h values is deducted from the h value of three angle points of tile.By these new h values of corner point, be configured to the saw tooth region that comprises sloped triangular shape (triangular flat surface elements).Be projected into the outer plane component excessively far away of x-y plane to be replaced by little face 5.This provide the region description for little face 5, Security element 1 of the present invention can be manufactured.

Surface 9 to be simulated can (x, y) – z=0 provides by mathematical formulae f (x, y, z)=h.Little face 5 or their orientation obtain from the tangent plane on surface 9 to be simulated.These can be determined from the mathematical derivation of function f (x, y, z).Be attached at an x 0, y 0the little face 5 at place is described by normal vector:

n → = n x n y n z = ∂ f ∂ x ( x 0 , y 0 , z 0 ) ∂ f ∂ y ( x 0 , y 0 , z 0 ) ∂ f ∂ z ( x 0 , y 0 , z 0 ) / ( ∂ f ∂ x ( x 0 , y 0 , z 0 ) ) 2 + ( ∂ f ∂ y ( x 0 , y 0 , z 0 ) ) 2 + ( ∂ f ∂ z ( x 0 , y 0 , z 0 ) ) 2

The azimuth angle alpha of tangent plane is arctan (n y/ n x), and the inclination angle σ of tangent plane is arccos n z.Region f (x, y, z) can be bending arbitrarily, and (x 0, y 0, z 0) be point on region, calculating is carried out for this point.Continuously for being selected for calculating a little of broached-tooth design.

Cut out regional with the normal vector so calculated respectively from clinoplain, its institute reconnaissance place in an x-y plane connects, when adjacent x-y point, to avoid the overlap of associated components.Appear clinoplain element far away to x-y plane evagination and be divided into less little face 5, as described with reference to fig 7.

Treat simulation surface can be described by triangle area constituent element, wherein flat triangular constituent element is across between institute's reconnaissance, the reconnaissance of described institute be positioned at waits simulate surface, and be positioned at wait simulate surface edge on.Triangle can be described as plane constituent element by following mathematical function f (x, y, z)

f ( x , y , z ) = x - x 1 y - y 1 z - z 1 x 2 - x 1 y 2 - y 1 z 2 - z 1 x 2 - x 1 y 3 - y 1 z 3 - z 1 = 0 ,

Wherein x i, y i, z iit is leg-of-mutton angle point.

In this case, region can protrude through in x-y plane and the individual triangle according to their normal vector inclination.The plane constituent element tilted forms little, and is divided into less little face 5 when they appear far away to x-y plane evagination, as described with reference to figure 7.

When being provided by triangle area constituent element wait the surface of simulating, someone also can carry out as follows.Whole surface to be simulated all (or the unit on each surface) is simultaneously subject to Fresnel and builds modulus d (or modulus d i).Because surface to be simulated is made up of plane constituent element, so the triangle of being filled by little face 5 automatically occurs on the x-y plane.

The structure of little also can carry out as follows.Limit in the x-y plane waiting to simulate surface 9 above it, suitable x-y point is selected and connects into and produces with polygon tile (tile) the area covering of x-y plane.In any selected element (such as angle point) top of each tile, from the upper side treat that normal vector 9 is determined in simulation surface.In each tile, be attached with now the Fresnel reflecting mirror (there is the pixel 4 in several little face 5) corresponding to normal vector.

Preferably, square tile or pixel 4 is applied.But the tiling (tiling) of (irregular) is all possible arbitrarily in principle.Tile can (this be preferred, because larger efficiency) adjacent to each other, or can have joint (such as when circular tile) between tile.

The inclination angle σ of plane can be expressed as follows:

σ = arccos n z = ar cos ∂ f ∂ z / ( ∂ f ∂ x ) 2 + ( ∂ f ∂ x ) 2 + ( ∂ f ∂ z ) 2

The azimuth angle alpha on inclined-plane can be expressed as follows:

α = arctan ( n y / n x ) = arctan ∂ f ∂ y / ∂ f ∂ x

Wherein for n y>0 α=0 ° to 180 °, and for n y<0 α=180 are ° to 360 °.

Determine that little face 5 comprises their orientation according to the present invention, can with two kinds substantially diverse ways carry out.Therefore, x-y plane can be divided into pixel 4 (or tile), and for each pixel 4, to reflectivity flat site determination normal vector, so described reflectivity flat site is converted into the identical several little face 5 of orientation.Alternatively, can come, close to surface 9 to be simulated, if it is not also provided by plane constituent element, then plane constituent element to be divided into individual little face 5 by plane constituent element.

In the first program, therefore first determine the tiling in x-y plane.Tiling can definitely at random configure.But the identical square that also possible that tiling is only a by the length of side is formed, and wherein a is preferably in the scope of 10-100 μm.But tiling also can be made up of difform tile, and these tiles are just in time combined together or there is joint.Tile can form differently, and comprises coding or the project that hides Info.Especially, tile can be adjusted to and be suitable for treating that simulation surface is to the projection in x-y plane.

So limit datum mark in any way in each tile.Be arranged in and wait that the normal vector at the some place of simulating above the datum mark being vertically positioned at tile on surface is associated with corresponding tile.If be arranged in above datum mark waiting simulate surface, several normal vector is associated with datum mark (such as at the edge that several area constituent element abuts or angle place), then can determine average normal vector from these normal vectors.

Subregion is limited in each tile in an x-y plane.This subregion can be arbitrary.From normal vector, so calculate azimuth angle alpha and inclination angle σ.Alternatively, also can limit offset system, it is to each little face 5 allocation offsets amount (height value).Side-play amount can be arbitrary in each region of subregion.But, also side-play amount can be applied to and make the maximum of the mean value in little face 5 all in identical At The Height or all little faces 5 at identical At The Height.

Be associated in the subregion in tile, so with the account form plane constituent element that be attached with inclination the same as little face 5, be associated with tile with normal vector, and take into account offset system.Then the surface configuration so calculated is formed in the surface 7 of carrier 8.

But, not only can limit any subregion in each tile in an x-y plane.Therefore, such as grid stroke can also be limited, described grid stroke roughly or just in time perpendicular to normal vector to the projection in x-y plane.Grid stroke can have arbitrary interval.But also possibly certain pattern is followed at the interval of grid stroke.Therefore, grid stroke can be arranged to not be such as just in time parallel to each other, to avoid such as interfering.But, but also can be that grid stroke is parallel to each other has different intervals.The different interval of grid stroke can comprise coding.In addition, likely the grid stroke in all little faces 5 has equal interval in each pixel 4.Interval can in the scope of 1 μm-20 μm.

Grid stroke can also have equal interval in each tile or in each pixel 4, but different between each pixel 4.Be associated the grid stroke interval Λ in little face 5 iwith inclination angle σ idetermine structural thickness d iitan σ i, wherein d ibe preferably 1-10 μm.

Little face 5 all can also possess phase co-altitude d.So by the inclination angle σ of little the i that be associated igrating constant is determined: Λ in the mode based on region i=d/tan σ i.

From normal vector, so again determine azimuth angle alpha and inclination angle σ.The sawtooth grating limited by grid stroke, azimuth and inclination angle are attached to account form when considering offset system and are associated in tile.

Also can from being made up of plane constituent element i (or be processed into make it form self by plane constituent element i) treat that simulation surface 9 starts, wherein wait that the size simulating surperficial constructional depth and plane constituent element is significantly greater than d i.

Such as, plane constituent element i is respectively by three angle point x 1i, y 1i, z 1i; x 2i, y 2i, z 2i; x 3i, y 3i, z 3iprovide.

For the answer of z, this obtains

z = z 1 , i + ( y - y 1 , i ) &CenterDot; x 2 , i - x 1 , i z 2 , i - z 1 , i x 3 , i - x 1 , i z 3 , i - z 1 , i - ( x - x 1 , i ) &CenterDot; y 2 , i - y 1 , i z 2 , i - z 1 , i y 3 , i - y 1 , i z 3 , i - z 1 , i x 2 , i - x 1 , i y 2 , i - y 1 , i x 3 , i - x 1 , i y 3 , i - y 1 , i

Its structural thickness in the i of region is less than d irequired saw tooth region by z modulus d iproduce, wherein z goes out from above formulae discovery, and wherein x and y value lays respectively in x-y plane by x when calculating 1i, y 1i; x 2i, y 2i; x 3i, y 3iin the triangle provided.

The saw tooth region so calculated automatically is made up of little face 5.As the grating constant Λ in the i of region iobtain

Λ i=d i/tanσ i

If expect equal grating constant Λ everywhere, then will insert following d i:

d i=Λtanσ i

Wherein σ iby x 1i, y 1i, z 1i; x 2i, y 2i, z 2i; x 3i, y 3i, z 3ithe leg-of-mutton inclination angle provided.

Following alternative program is possible.In following formula A, be positioned at and treat that simulation surface 9 is described by triangle projective planum constituent element above x-y plane

Plane constituent element i is respectively by three angle point x 1i, y 1i, z 1i; x 2i, y 2i, z 2i; x 3i, y 3i, z 3iprovide.

Angle point is numbered into and makes z 1ithree value z 1i, z 2i, z 3iin minimum of a value (z 1i=min (z 1i, z 2i, z 3i)).

Following formula B represents the saw tooth region waiting the three dimensional impression simulating surface 9 that simulation is provided by formula A.

Can find out, according to the saw tooth region of formula B with treat that the difference of simulated domain is the minimum of a value z in the i of region according to formula A 1ideducted from value z respectively.Saw tooth region according to formula B is made up of the sloped triangular shape being attached to x-y plane.

As the maximum gauge d for constructional depth iwhen being determined in advance, likely maximum gauge is being exceeded according in the saw tooth region of formula B.This can pass through according to z modulus d iform little of the individuality with identical normal vector to be made up, wherein z calculates from above formula B, and x and y value lays respectively in x-y plane by x when calculating 1i, y 1i; x 2i, y 2i; x 3i, y 3iin the triangle provided.

The saw tooth region so calculated is made up of the delta-shaped region being filled with little face 5, and the grating constant Λ wherein in the i of region is as Λ i=d i/ tan σ iobtain.Angle σ iby x 1i, y 1i, z 1i; x 2i, y 2i, z 2i; x 3i, y 3i, z 3ithe leg-of-mutton inclination angle provided.

Here for described by triangle and the program simulated shown by surface of waiting being converted into the pixel 4 with several little face 5 according to the present invention should exemplarily understand.Generally speaking, when treating that simulation surface is described by plane constituent element, carry out as follows according to the present invention.Plane constituent element is divided into multiple unit.When splitting, deduct a value (the minimum of a value z in such as unit).Therefore according to present invention obtains so a kind of sawtooth grating, it is than treating that simulation surface 9 is more flat, and it has identical normal vector respectively in the mode based on region in each unit.

This sawtooth grating imitates initial surface 9 to be simulated, and comprises its three dimensional impression.This sawtooth grid ratio is more flat by the sawtooth grating of identical Program Generating when not pixel 4 not being divided into several little face 5 according to the present invention.

Figure 10 illustrates the top view of three pixels 4 in the region 3 of an embodiment again, wherein pixel 4 forms (solid line) brokenly, has irregular subregion or little face 5 (dotted line).Pixel edge and subregion are here straight lines, but they also can be bending.

Figure 11 illustrates corresponding sectional view, wherein schematically illustrate the normal vector in little face 5.For each pixel 4, the normal vector in whole little face 5 is identical, but they are different between pixel 4.Normal vector is tilt in space, and usually not in drawing, as in Figure 11 for succinct therefore illustrate.

Figure 12 illustrates the top view that the segmentation of pixel 4 is the same with Figure 11, but wherein the subregion (little face 5) of each pixel 4 is different.In the embodiment shown, the grating period A in little face 5 is constant in each pixel 4, but is different between pixel 4.

Figure 13 shows corresponding sectional view.

Figure 14 illustrates another modification, wherein the same with Figure 10 of pixel form.But the subregion of each pixel 4 is encoded.Every second grid stroke interval is that the twice at last grid stroke interval is large.Figure 15 illustrates corresponding sectional view.

n &RightArrow; trans = cos &phi; 0 sin &phi; 0 1 0 - sin &phi; 0 cos &phi; &CenterDot; n &RightArrow;

Wherein, on normal vector.

Security element 1 of the present invention not only can be configured to reflective security element 1, but also can be configured to transmittance Security element 1, as mentioned above.In this case, little face 5 is not applied by mirror film, and carrier 8 is made up of transparent or at least translucent material, realizes thus observing in transmission.When from back side illumination, user should feel that simulation surface 9 seems that existence is the same from the reflective security element 1 of the present invention of front side-illuminated.

The data that the little face 5 calculated for reflective security element 1 is used to microprism 16 replace, and wherein respective angles illustrates when reflecting (Figure 19) and for the transmittance prism 16 in Figure 20 and 21.Figure 20 shows the incidence to tilting on little face 5, and Figure 21 shows to the incidence in smooth side, and the latter is preferred, because larger incident angle of light becomes possibility.

The azimuth in the little face 5 of reflectivity is by α srepresentative, and the inclination angle in little face 5 is by σ srepresentative.The refractive index of microprism 16 is n, and the azimuth of microprism 16 is α p=180 ° of+α s.Be sin (σ according to the inclination angle of the microprism 16 of Figure 20 p+ 2 σ s)=n sin σ p, wherein 2 σ are set up for low-angle s=(n-1) σ pwith 4 σ sp(for n=1.5).

Be sin (2 σ according to the inclination angle of the microprism 16 of Figure 21 s)=n sin β; Sin (σ p)=n sin (σ p-β), wherein 4 σ are set up for low-angle sp(for n=1.5).

When α and σ is known, the component of normal vector is

n z=cosσ,n y/n x=sinα/cosα,n x 2+n y 2+n z 2=1

n x = cos &alpha; &CenterDot; 1 - cos 2 &sigma; , n y = sin &alpha; &CenterDot; 1 - cos 2 &sigma;

Schematically show in fig. 22 there is peak portion 20 and depression 21 treat simulated reflections face 9.Negative focal length-the f in mirror reflectivity peak portion 20 is r/2, and the positive focal length f of mirror reflectivity depression 21 is r/2.

Schematically show lens 22 in fig 23, it has transparent recess 23 and transparent protuberance 24.Recess 23 simulates mirror reflectivity peak portion 20, and the negative focal length-f of its center dant 23 is 2r.Transparent protuberance 24 simulates mirror reflectivity depression 21, and has positive focal length f=2r.

Lens 22 according to Figure 23 can be replaced by the saw-tooth arrangement according to Figure 24.

Arrow in Figure 20-23 schematically shows the ray tracing of incident light L.It is evident that from these ray tracings, lens 22 are simulation surperficial 9 as required in transmission.

In Figure 25-27, illustrated that sawtooth side is positioned at the example of light incident side.Other side, the diagram of Figure 25 corresponds to the diagram of Figure 22, and the diagram of Figure 26 corresponds to the diagram in Figure 23, and the diagram of Figure 27 corresponds to the diagram in Figure 24.

In order to calculate transmittance broached-tooth design, said method can be adopted.

Transparent broached-tooth design shown in Figure 27 roughly corresponds to the moulding (cast) of the corresponding reflectivity broached-tooth design for simulating surface 9 according to Figure 25.But simulation surface is middle than roughly presenting get Geng Ping in reflection in transmission (refractive indexes with 1.5) here.Therefore, the height of broached-tooth design preferably increases, or the quantity in the little face 5 of each pixel 4 increases.

Semitransparent mirror membrane coat can certainly be set for described broached-tooth design.In this case, simulation surface 9 presents the structuring comparing deeper degree in transmission in reflection usually.

In addition, can also arrange broached-tooth design for the both sides of transparent or at least translucent carrier 8, this broached-tooth design has multiple microprism 16, as shown in Figure 28 and 29.In Figure 28, the broached-tooth design 25,26 of both sides is Mirror Symmetries.In Figure 29, two broached-tooth designs 25,27 are not Mirror Symmetry structures.

In order to calculate the broached-tooth design 25 and 27 according to Figure 28 and 29, can suppose that broached-tooth design 25,27 is by having inclination angle σ pprism surface 28 and attachment thereunder there is inclination angle σ hauxiliary prism 29 form, as schematically shown in Figure 30.Therefore, σ p+ σ hit is effective total prism angle.

When relief inclination angle to be imitated is designated as σ stime, because the angle summation in triangle is 180 °, therefore following establishment:

90°-β1+90°-β2+σ ph=180°

σ ph=β1+β2,

From the law of refraction

sinσ p=n sinβ1,sin(2σ sh)=n sinβ2

Obtain

σ p-arcsin((sinσ p)/n)=arcsin((sin(2σ sh))/n)-σ h

Therefore, with such as predetermined auxiliary prism inclination angle σ hfrom relief inclination angle σ to be imitated sstart, the required inclination angle σ of prism surface 28 can be calculated like a cork p.

It should be noted, it is assumed that right-angle view in the calculating of stating for being imitated minute surface relief by prism.May distort during oblique view, and colour edging when observing in white light, may be obtained on represented figure, because the refractive index n entering calculating depends on wavelength.

When speculum embeds after in hyaline layer 40, the direction presenting mirror image changes, as shown in Figure 32 b.If now will by embed micro-reflector 5 simulate relief in obtain original reflective effect, then for micro-reflector inclination angle this will include consideration in, see Figure 32 c.

Example: the prism of embedding

For the prism 16 embedded, the refractive index difference between prism material and embedding material 40 is required, and is considered in the calculating of beam deflection.

The transmittance prism that Figure 33 b schematically shows by having open prism 16 configures the simulation configured the reflectivity of Figure 32 a, as such as discussed Figure 19-27.

Figure 33 b schematically shows may simulating of the reflectivity configuration of the prism 16 couples of Figure 32 a by embedding, and wherein prism material and embedding must be different by the refractive index of material 40.
